Abstract
The utility model provides a joint bearing which relates to engineering machinery of a road surface. The inner cambered surface of an outer ring of a bearing is provided with a closed curve oil groove which has the same caliber as that of an inner annular oil groove, and lubricating grease enters the frictional spherical surface through the annular oil groove of an inner ring and a radial hole and then lubricates the whole frictional spherical surface through the curve oil groove of the inner cambered surface of the outer ring. The joint bearing can make the lubricating grease enter a load-bearing friction surface to improve the lubricating effect of the joint bearing, eliminates noise and extends the service life of the bearing.
Description
Technical field
The utility model relates to a kind of field of road engineering machinery.
Background technique
Used GB joint shaft bearing oil groove is in the middle part of joint shaft bearing inner ring endoporus middle part and outer ring cylindrical annular oil groove to be arranged at present, has radial direction oil hole to be communicated with inside and outside circle annular oil groove then.This kind joint shaft bearing when bearing radial load and relatively rotating because the bearing outer ring inner sphere radius (in the R) greater than bearing inner race outer spherical surface radius (R is outer), there is the gap in promptly inside and outside circle friction sphere, can guarantee the injection lubricant grease, the prolongation bearing life.But when joint shaft bearing bore thrust load and relatively rotates, the displacement vertically of the inside and outside circle of bearing formed a circular seal line greater than outside the R because R is interior, and the carrying rubbing surface can't enter lubricating grease, and bearing life is low, occurs sound sometimes.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel joint shaft bearing, solves prior art carrying rubbing surface and can't enter lubricating grease, and bearing life is low, occurs the problem of sound sometimes.
The technological scheme that its technical problem that solves the utility model adopts is: by at the bearing outer ring intrados closed curve oil groove being set, the curve oil groove is identical with interior annular oil groove bore, make lubricating grease through inner ring annular oil groove and radial hole engaging friction sphere, then through the curve Sump lubrication of the outer ring intrados sphere that all rubs.
Adopt good effect of the present utility model to be; Can make lubricating grease enter the carrying rubbing surface, improve the joint shaft bearing lubrication effect, eliminate noise, prolong bearing working life.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
1 is that bearing outer ring, 2 is that bearing inner race, 3 is that inner ring annular oil groove, 4 is outer ring closed curve oil groove among the figure.
Embodiment
The bore of this novel joint shaft bearing outer ring closed curve oil groove (4) is identical with inner ring annular oil groove (3), after machining bearing outer ring (1) and bearing inner race (2) is fitted together and promptly can be applicable to field of road engineering machinery.
Claims (1)
1, a kind of joint shaft bearing is characterized in that at the bearing outer ring intrados closed curve oil groove being set, and the curve oil groove is identical with interior annular oil groove bore, constitutes new-type joint shaft bearing.
